I just bought a Allis Chalmers M100B road grader. The folks told me that it was running and then just quit. It has been sitting for awhile now and I am going to give a shot at making it run again.
This is what I have so far (new to this beast so bare with me). The fuel line from the tank hits two fuel filters that are about two inchs above the tank outlet (I guess that fuel must be above a certain level before you may use it). Then the line runs to the "IN" on the top of the Roosa Master DBG pump.
There is one line on the bottom that is connected to the "OUT" fitting on the pump and appears to go to a gauge inside for Fuel Pressure.
There is one line that comes out of the top of the pump that connects with a tee from the injectors and connects to the return on the fuel tank.
There is six lines from the pump that travel to the injectors.
Here is where I am getting a little confused. Does the fuel connecting to the IN on the pump have to be pumped (under pressure) or is the gravity fed system correct? If the gravity fed system is correct, then is the end part of the pump with the fuel IN and the OUT on bottom the pump? If so, then if I have good fuel flow to the IN, getting small drips of fuel on the OUT and nothing at all coming out of any of the injector or top return lines, then is it possible I just have a bad pump?
I appreciate your help with this and anyone with pics of schmetics or anything they would like to share, PLEASE do so. I haven't yet ordered a manual for rebulding this pump because I am not sure which would be best, so any input on this would be great too.

Today's Featured Article - Talk of the Town: What's The "Stuckest" You've Ever Been? - by Edited by Kim Pratt. Another great discussion from the Tractor Talk Discussion Forum. The discussion started out with the following post: "I was about 14 (part of the problem) when I got stuck. I was disking with a cab equipped IH 966. The window was dirty and I was driving into the evening sun. It was hard to see and it was my first pass down the field. I got the tractor so stuck that the underside of the tractor was resting on the ground. My uncle wanted
